Bruce Vining - Would you Please Comment On This

[bvining@xxxxxxxxxxxx]

I'm not sure which part of the note you are asking for comment on, but
will try to cover both CPW and TPC-C.  I will also throw in the
disclaimer that I am not in the performance area, but did make a few
phone calls...

First, CPW is a measured workload that is run/benchmarked on each AS/400
model.  CPW ratings do not appear to exist for platforms other than
AS/400.

TPC-C, on the other hand, is a measured workload that is run/benchmarked
on selected models of AS/400.  When you see published TPC-C numbers for
a model, they represent an actual measurement audited by the TPC.

As a general rule of thumb, one can approximate TPC-C numbers for models
that were not explicitly measured by multiplying the measured CPW by 10.
You would not however find these approximate TPC-C values published
anywhere.
